Question
A takes 3 hours more while swimming upstream than
downstream. His speed in still water is 12 km/hr. The speed of stream is 4 km/hr. What is the distance?Solution
Let A’s speed be x km/hr and current speed be y km/hr. Downstream speed = x + y = 12 + 4 = 16 km/hr Upstream speed = x – y = 12 – 4 = 8 km/hr Let time taken for downstream be ‘t’ hours. Here distance is same. => 16 × t = 8 × (t + 3) => t = 3 hrs Distance = 16 × 3 = 48 km
